Application filed December 29, 1916. Serial No. 139,474.

T0 all 'whom it may concern.'

Be it known that Wey and snDoRn FLEIsoHMAN, citizens of the United States, and residing at Jersey City, in the county oli Hudson and State of New Jersey, have invented certain new and uselfullmprovements in Automobile-Radiators, of which the following is a speciiication, such as will enable those skilled in the art to Which it appertains to make and use the saine.

. This invention relates to the radiators of automobiles, and the object thereof is to improve the construction of devices of this classl so as to 'facilitate' the repair thereof When necessary. The invention is fully disclosed inthe following specification, of which the accompanying drawing, forms a part, in which the separate parts of our improvement are designated by suitable reference characters in each of the views, and in Whicli:-

Figure l is a view of a part of the front end of an automobile radiator constructed aecprding to our invention, but on a reduced scale;

Fig. 2 a similar View on an enlarged scale and showing the details of our improvement;

Fig. 3 a transverse sectional view on the line 3-3 or' Fig. 2;'and,

Fig; l an end vienT one of the sections oi the radiator.

The invention described and claimed herein is an improvement on that described and claimed in U. S, Letters Patent No. 975,3-l3 granted to Jacob 'Fleischman Nov. ll, 1910, and in the drawingq forming part oi' this specification, We have shown at a a part et' radiator of an automobile as usually constructed.

In forming or constructing radiators of the class speciied, it has been customary to forni the body or Water and air circulating portion a of separate vertically arranged sections Z) of sheet metal composed of separate sidep parts brought together and secured together at the top and bottom, or of a singlesheet of'inetal folded centrally so as to bring the ends thereof together, and when said sections Were made of separate parts brought together' at the top and bottom they were soldered together at said top and bottom, and. when Said sections Were formed from a single sheet folded and the ends thereof brought together, they were JACOB FLEISCHMAN oi' the parts of the sections Z), and these points were neces! sarily built up in the Water tanks or, chambers at the top and in order to solder these leaks or make repairs it was necessary to detach the separate parts of the framework oi the radiators or detach the top and bottom Water tanks or chambers, and thiswas a didicult and expensive operation by reason of the fact that the framework or casing of such radiators is usually made of separate parts connected at at, a4 and a5 and the connection of such parts at the points named being made by soldering. i

As above stated the operation of re-solder ingl or repairing the separate sections of the radiator under the conditions named was a diflicult and expensive operation, and the object of'this invention is to dolaway with this diiliculty and to render the re-soldering or repairing of the radiator or radiators more simple and inexpensive.

It is a Wellknown fact that leaks in radiiators of this class occur almost universally at the points Where the parts of the separate sections o of the radiators are soldered together and in order to avoid the objections herein set out We forro. the separate sections Z1 from a single sheet of metal, Which is first stamped to form in one side thereof spaced transverse grooves b2 connected by Webs IJ", and both end portions' of the sheet thus formed are folded at predetermined points so as to bring the ends thereof together, as shown at 214 in Fig. ii'olded or interlocked and soldered together in the usual manner.

This brings the soldering together of the end portions of the sheet from which the separate sections Z) are formed at some point between the ends thereof according to the folding oi the end portions of said sheet or the points at which they are folded, and this connection of said end portions may be on either side of the sections as Will be readily understood.

With our invention the folding of the end portions of the sheet from which the and bottom of the radiator,

or later Were at f fi, and saidends are then any other devices o' fthis ployed which wiil -neetion at o, and the ame of a torchV is vdirected through the air aperture or space,

and this melts the soldering material and solders and renders both air and Water-tight ythe connection at' b4 of the end portions of the sheet or sheets from which the separate sections or' the radiator are made.

lt Will be understood that the radiator body is inade up in the same manner as in the patenthereinbefore referred tog or as class, and is provided with the usual air spaces or passages 55 and with the usual Water circulating spaces or passages Zi, and the separate sections b which forni the body or honeycomb Work of vthe radiator 'are connected as in said patent andas in other devices of this class.

The object or' arranging the points of' con- LLeotion at 5* of the ends of the sheets from which the separate sections ot the radiator are formed shown is bring said point of eonneetion of one see-tion at suche die tance from the corr vending o other section or sections that in the point of son action of one seotion7 the corresponding point or another 'section will not be overheated and -ose a loa-ln and While We prefer te o 'the points oi? connection at 64',- o b in staggered relaIA s any arrangement' this gcass n'iay be enn seien as not to brin.;

the said points of connection at 5'* of any two sections closely together or in the saine' transverse` line. i

With our improvement, as hereinbefore stated, We avoid the necessity of disconnecting the parts of the radiator frame or easingV in order to repair leaks in the seotions b'which make up the body of the radiator, and in this Way vthe expense of resoldering is rendered a eomparatively sirnple operation. and one which can be much more expeditiously performed and at a minimum of expense Compared with that necessary with' radiate of this class as usually constructed.

Having fully described our invention, what we claim as new and desire to secure by Letters Patent, is s n a radiator of the elass described, a

body portion consisting of separate verticallyarranged sections, eaeh of Whichextend `from the top to the bottom of the radiator7 each of said sections bei g conv posed of a single sheet of metal having 'its extremities folded so as to bring' the ends of the sheet together at a uredetemnined point intermediate the ends of the section, said ends beine' joined together, ti e joint of one of the-seetions being out or horizontal alineinent with the joints of adjacent sections, whereby the joint of one section may he 'repaired 'withcait afleoting the joints of adjacent sectionN v s t iniony that we elaiin the foregoing' our invention We have signed our names,
